Whilst the accidental ingestion of foreign bodies is common, the incidence of gastrointestinal perforation from foreign bodies is reported to be <1%.[[1]] Most ingested foreign bodies pass through the gastrointestinal tract without incidence; however, objects with sharp edges such as fish bones, chicken bones and toothpicks can cause perforation.[3] Blister packaged pills (BPPs) are being increasingly reported as a cause of gastrointestinal perforation.[[1], [3]] BPPs, also known as press-through packages, account for 85% of the packaging for all solid medications in Europe.[4] They are made up of a dome-like cavity usually formed by thermoformed plastic and enclosed by a lid of aluminium foil.[[4]] The individual portions of the BPP can be divided and the sharp edges of the aluminium lid can cause damage to the gastrointestinal tract if ingested.[[5], [7]] In this study, we report a case of ileal perforation caused by the inadvertent ingestion of a BPP. A non-contrast computed tomography (CT) performed revealed pneumoperitoneum and free fluid surrounding the liver as well as diverticular disease, but no clear site of perforation.
